Zhang Mengyao felt the explanation about the Game was unnecessary at this point. They had gone through the Game for almost a year, and it did not matter anymore the reason why the Game started. If she wanted to know something, it was the purpose of the Game. However, she could get the answer from that little explanation. The Game was made for people with no power.
Zhang Mengyao had gone through several Survival Games, and she had seen the other worlds. Whether the world that had gone through the Game or the world that had yet to experience the Game. She found that the humans in the other worlds were more powerful than them. They could use mana and spell without the help of the system.
Through the system, the strong get stronger, but the weak could catch up to the strong. In other words, the Game was a tool to balance the worlds, giving a chance for everyone to have equal power. Zhang Mengyao interpreted the Game that way after a little explanation from the System.
